| Abstract/Contents: | "Winter over-seeding of warm-season turf with cool season grasses improves the appearance and playability of golf courses located in subtropical climates. Plant growths regulators are often applied to warm-season turf prior to over-seeding to increase the competitive ability of the over-seeded grass and enhance establishment. Chemical treatments may also be used to control cool-season weed species such as Poa annua L. Little is known about the effect of these chemicals on cool-season grass seed germination. The objective of this study was to test the germination response of four cool-season grasses under ideal conditions and compare those tests with seeds treated with growth regulators and a selective herbicide used for Poa annua control. Seed blends of perennial ryegrass (Lolium perenne), creeping bent (Agrostis stolonifera L.), Poa trivialis L., or Poa annua were treated with pure water or solutions of trinexozpac-ethyl, flurprimidol, or ethofumesate using three application methods. These samples were then germinated according to the recommendations of the Association of Official Seed Analysts (AOSA). Results indicated significant germination inhibition of all species by each chemical tested. Trinexapac-ethyl inhibited germination more severely than either flurprimidol or ethofumesate. Germination inhibition was directly related to the length of time each chemical was in contact with the seed and higher chemical concentrations resulted in greater inihibition." |
